Titanium gypsum ndi mtundu wa zinyalala zomwe zimakhala ndi dihydrate gypsum ngati gawo lalikulu, lomwe limapangidwa powonjezera laimu (kapena calcium carbonate) kuti lichepetse madzi ambiri otayika a asidi kuti lichiritse madzi otayika a asidi pamene titanium dioxide imapangidwa ndi njira ya sulfuric acid. Kutuluka kwa titanium gypsum sikuti kumangotenga malo ambiri ndikuipitsa chilengedwe, komanso kumabweretsa mavuto azachuma kwa makampani a titanium dioxide. Titanium gypsum ingagwiritsidwe ntchito kupanga simenti yobwezeretsa pambuyo pokonzedwa ndi makina opera. Guilin Hongcheng ndi katswiri wopanga zinthu.titaniyamumphero yopukusira gypsum.Zotsatirazi zikufotokoza momwe mungakonzekerere zinthu zopangidwa ndi simenti ya titaniyamu ya gypsum yokhala ndi magwiridwe antchito abwino.

1. Kodi kuwonjezera zinthu zosiyanasiyana mu titaniyamu gypsum kumakhudza bwanji magwiridwe antchito ake?

Mphamvu ya titaniyamu gypsum ikasinthidwa thupi imakhala ndi mpata wina ndi ya gypsum yachilengedwe ndi gypsum ina ya mankhwala. Zowonjezera zina ziyenera kuwonjezeredwa kuti ziwongolere mphamvu ya titaniyamu gypsum. Zowonjezera zomwe zimagwiritsidwa ntchito ndi monga phulusa losungunuka, phulusa louluka, slag yozimitsidwa ndi madzi, alum, chochepetsera madzi ndi choletsa.

Ngati slag yozimitsidwa ndi madzi imagwiritsidwa ntchito ngati chophatikiza chopepuka, pamene kuchuluka kwake kuli kochepera 40%, sikukhudza mphamvu ya chinthu cha titanium gypsum, ndipo imatha kuchepetsa kuchuluka kwa zinthuzo; Ngati kuchuluka kwa phulusa la ntchentche kuli kochepera 30%, kumakhudza pang'ono mphamvu ya titanium gypsum, koma pamene kuchuluka kwa phulusa la ntchentche kuli koposa 30%, kumachepetsa mphamvu ya titanium gypsum, ndipo phulusa la ntchentche limathandiza kukweza mphamvu ya titanium gypsum (7d). Phulusa losungunuka limatha kukweza kwambiri mphamvu ya titanium gypsum. Ndi kuwonjezeka kwa kuchuluka kwake, mphamvu ya zinthu za titanium gypsum imatha kukwera kwambiri. Alum imatha kukweza bwino mphamvu ya titanium gypsum, ndipo pamene kuchuluka kwake kuli 3%, zotsatira zake zimakhala zabwino kwambiri; Kuchuluka kwa madzi owonjezeredwa kumakhudza mphamvu ya titanium gypsum. Ndi kuwonjezeka kwa kuchuluka kwa madzi owonjezeredwa, mphamvu ya chitsanzo imachepa kwambiri. Chifukwa chake, pamene tikutsimikiza kuti phala la gypsum limatuluka, kuchuluka kwa madzi owonjezeredwa kumakhala kotsika, kumakhala bwino.

Monga chophatikiza chopepuka, slag yozimitsidwa ndi madzi imatha kukweza kuchuluka kwa zinthu zoyeserera za titanium gypsum. Phulusa losungunuka, phulusa losungunuka ndi alum zimatha kukweza kwambiri mphamvu ya titanium gypsum. Chifukwa chake, titanium gypsum, phulusa losungunuka ndi phulusa losungunuka zimasankhidwa ngati ufa, slag yozimitsidwa ndi madzi imagwiritsidwa ntchito ngati chophatikiza chopepuka, ndipo alum, melamine ndi citric acid zimagwiritsidwa ntchito ngati zowonjezera. Ma parameter abwino amapezeka posintha gawo la ufa. Gawo la chophatikiza ndi 40% ya ufa, gawo la alum mu chowonjezera ndi 3% ya ufa, gawo la melamine ndi citric acid ndi 1% motsatana, ndipo kuwonjezera titanium gypsum 70% ndi phulusa losungunuka ndi 30%, magwiridwe antchito a simenti ndi abwino.

2. Kodi mungakonzekere bwanji titaniyamu gypsum composite simenti yokhala ndi magwiridwe antchito abwino?

Pambuyo pokonza calcining kwa maola awiri pa 600℃, titanium gypsum imaphatikizidwa ndi phulusa la ntchentche, slag ndi simenti kuti ifupikitse nthawi yoyambira yokhazikitsa composite kufika pa maola atatu, nthawi yomaliza yokhazikitsa kufika pa maola asanu, ndipo mphamvu ya 28d flexural ndi mphamvu yokakamiza imafika pa 4.3MPa ndi 13.6MPa motsatana. Ndi titanium gypsum ndi slag ngati zinthu zoyambira, simenti clinker ndi composite early strength water reducer zitha kugwiritsidwa ntchito kukonzekera simenti ndi ntchito yabwino kwambiri, ndipo mphamvu yake ndi kukana madzi ndizowoneka bwino kuposa za gypsum yomanga. Kafukufukuyu akuwonetsa kuti mphamvu ya titanium gypsum mixed cementitious material pambuyo pokonza mwachilengedwe kwa masiku 28 ikhoza kukwaniritsa zofunikira za zipangizo zomangira makoma ndi zinthu zosakanikirana za municipal road subgrade, kuchuluka kwake kosungunuka ndi kochepera 20% ya building gypsum, ndipo kuchuluka kwake koyamwa madzi ndi pafupifupi 50% ya building gypsum, zomwe zikusonyeza kuti titanium gypsum composite cementitious material ili ndi kukana bwino madzi. Ngati titanium gypsum fly ash slag composite cementitious material sichisakanizidwa ndi activator, nthawi yake yokhazikitsa ndi yayitali ndipo mphamvu yake yoyambirira ndi yochepa. Kuwonjezera simenti yokwanira ku simenti yophatikizana iyi kungachepetse nthawi yokhazikika ya simenti yophatikizana, zomwe zimathandiza kukula kwa mphamvu ya simenti yophatikizana.

Zotsatira zina za kafukufuku zikusonyeza kuti kuwonjezera simenti ya 5% ku titanium gypsum fly ash slag composite simenti kungafupikitse nthawi yoyambira yokhazikitsa zinthu zophatikizana kukhala maola 4, nthawi yomaliza yokhazikitsa kukhala maola 9, ndipo mphamvu ya 28d flexural ndi mphamvu yokakamiza zimatha kufika 5.8MPa ndi 29.OMPa motsatana. Zipangizo zophatikizana zogwira ntchito bwino zitha kukonzedwa pogwiritsa ntchito titanium gypsum, fly ash, slag ndi simenti ya Portland kapena clinker pang'ono, kusankha choyambitsa choyenera ndikuchita njira zoyenera. Kafukufukuyu akusonyeza kuti kuwonjezera 5% alunite mu titanium gypsum fly ash slag composite simenti kungafupikitse nthawi yoyambira yokhazikitsa zinthu zophatikizana kukhala maola 1, nthawi yomaliza yokhazikitsa kukhala maola 2, ndipo mphamvu ya flexural 28d ndi mphamvu yokakamiza zimafika 9.5 MPa ndi 53.0 MPa motsatana, kufika pa mulingo wa mphamvu ya 525R slag Portland simenti.

3. Kodi mitundu yosiyanasiyana ya zoyambitsa zimakhudza bwanji mphamvu ya titaniyamu gypsum composite simenti?

Mphamvu ya zinthu zomangira zophatikizika zimatha kukwera kwambiri pambuyo pa kusungunuka kwa titanium gypsum. Mphamvu ya 28d ya zinthu zomangira zophatikizika zomwe zimayambitsidwa ndi simenti yokha idakwera ndi 70%, ndipo mphamvu yopindika ndi yopondereza ya zinthu zomangira zophatikizika idakwera ndi kuwonjezeka kwa simenti. Pamene kuchuluka kwa simenti kuli 15%, mphamvu yake imakhala yayikulu kwambiri. Pamene kuchuluka kwa laimu kuli 15%, kuchuluka kwa simenti kuli 0, ndipo mphamvu yake imakhala yotsika kwambiri. Mu dongosolo la phulusa la titanium gypsum fly phulusa, kugwiritsa ntchito simenti yochotsa mpweya kumathandiza kwambiri pakukweza mphamvu ya dongosololi.
